In undertaking cultivar trials, the variability of the response of the
cultivars to the different environments in which they are grown intro
duces the possibility of release errors and non-release errors in the
decisions made on the basis of the trial results. In this article a mo
del is developed that accounts for the economic costs of those errors
as well as the costs of operating the trials, and enables the features
of the optimal cultivar testing program to be identified. The model i
s illustrated by application to wheat cultivar trials in central and s
outhern NSW.
